Continuity: When Charles Bronson steps out on the balcony of the nazi villa a second time (after having to hide), he drops his rope (to get on the roof), and when we see him from another angle, he drops it again.

Continuity: In the scene where the four remaining guys finally cross over the bridge in the half-track, John Cassavetes gets shot dead by a Nazi soldier. The next shot shows the vehicle just crossing over the bridge again.

Factual error: When the Major shoots the rope out from under the slow soldier, the rounds should have gone through the floor but did not. There aren't even marks on the floor.

Continuity: When Waterslaw and Jefferson each shoot a soldier through a window, no glass seems to break until we see each soldier fall out through the glass.
